Fast delay estimation methods, as compared to simulation techniques, are needed for incremental performance-driven layout synthesis. On-chip inductive and conductive effects are becoming predominant in deep submicron (DSM) interconnects due to increasing clock speeds; circuit complexity and interconnect lengths. Inductance causes noise in the signal waveforms, which can adversely affect the performance of the circuit and signal integrity. Elmore delay-based estimation methods, although...

In this work, the end-to-end performance of an amplify-and-forward multi-antenna infrastructure-based relay (fixed relay) system over flat Rayleigh fading channel is investigated. New closed form expressions for the statistics of the received signal-to-noise ratio (SNR) are presented and applied for studying the outage probability and the average bit error rate of the digital receivers. The results reveal that the system performance improves significantly (roughly 3 dB) for M=2 over that for... Topics: Diversity, fading channel, moment generating function(mgf), outage probability.
